Bennett met the grieving parents on Monday (March 7) and is calling on the Prime Minister to "step in" and overturn the decision - as he did for Neil Shepherd and Sharon Wood whose two children died from carbon monoxide poisoning while on holiday in Corfu.

“Clearly there is huge amount of legal force from various parties represented at the inquest and Zane’s parents should have the same level of support,” she said.

“Having gone away I have learnt a lot of the broader issues around landfill and flooding and will be looking at that in the future. But there is an urgent and pressing need for this now.

"There are only a matter of months for a legal team to be prepared and they need to be starting now. Any parent is going to be thinking 'this could be me' and understand how you would want everything checked out.”
